RX-21 HD

The SampleScience RX-21 HD sample pack is a free high definition sample collection of the Yamaha RX-21 drum machine sounds. The RX-21 is a mid-eighties entry-level drum machine featuring one drum kit that can also be found on other Yamaha drum machine models (among them, the Yamaha RX-11 which has been used by Aphex Twin on his latest album and also on his previous double album Drukqs).

Included in the pack are the clean recordings of the RX-21 drum sounds in 16-bit, 24-bit, and 32-bit 44.1kHz Wav file format. As a bonus, we also added tube processed samples with 4 round robins and a cool 80s reverb version of the RX-21 drum kit.
